Staff Report for Resolution Rejecting All Bids for the Water Pollution Control Plant (WPCP) Asphalt Replacement, Project No. 2015.0260
Staffreport
SUMMARY AND RECOMMENDATIONS
The contract provided for repaving areas at the City's Water Pollution Control Plant (WPCP) site, which were not repaved as part of the WPCP Replacement Project and for installation of water and compressed air underground service piping for routine maintenance operations at various locations within the plant.
Staff recommends rejecting all bids from the August 10, 2017 bid opening for the subject project and rebidding the project during winter 2017.
BACKGROUND
The Water Pollution Control Plant (WPCP) is a 30 acre facility at the western end of Davis Street that treats sewage from approximately half the City so that it may be discharged to San Francisco Bay without risk to people or the environment. The recently completed WPCP Replacement project made improvements to many of the structures on site and included replacement of approximately one third of the onsite pavement. This new project will address the remaining deteriorated pavement surfaces in the facility.
Originally, the scope of this project was to repair or replace 2.6 acres of asphalt pavement. During the design of the project, staff identified an additional 0.3 acres for repair or replacement. WPCP staff also requested installation of approximately 1,300 linear feet of joint utility trench to provide compressed air and water to sixteen locations.
This project is intended to improve the pavement and drainage conditions throughout the facility and also improve staff efficiency by providing easier access to compressed air and water used for maintaining and operating the onsite equipment.
